Enclosing interface:

Mesh<F extends Mesh.Face>

public static interface Mesh.Face

Interface representing a single face in a mesh.

Method Summary

Modifier and Type	Method and Description
boolean	definesPolygon() Return true if the vertices for this face define a convex polygon with non-zero size.
int	getIndex() Get the 0-based index of the face in the mesh.
ConvexPolygon3D	getPolygon() Get the 3D polygon defined by this face.
int[]	getVertexIndices() Get an array containing the 0-based indices of the vertices defining this face.
List<Vector3D>	getVertices() Get the vertices for the face.

Method Detail

getIndex

int getIndex()

Get the 0-based index of the face in the mesh.

Returns:

the 0-based index of the face in the mesh

getVertexIndices

int[] getVertexIndices()

Get an array containing the 0-based indices of the vertices defining this face. The indices are references to the vertex positions in the mesh vertex list.

Returns:

an array containing the indices of the vertices defining this face

getVertices

List<Vector3D> getVertices()

Get the vertices for the face.

Returns:

the vertices for the face

definesPolygon

boolean definesPolygon()

Return true if the vertices for this face define a convex polygon with non-zero size.

Returns:

true if the vertices for this face define a convex polygon with non-zero size

getPolygon

ConvexPolygon3D getPolygon()

Get the 3D polygon defined by this face.

Returns:

the 3D polygon defined by this face

Throws:

IllegalArgumentException - if the vertices for the face do not define a polygon
